While mainstream AI may no longer ponder questions of humanity and intelligence, I find that this poem touches the essence of what it means to be human.
POEM

The spirit
  likes to dress up like this:
    ten fingers, 
      ten toes,

shoulders, and all the rest
  at night
    in the black branches,
      in the morning

in the blue branches
  of the world.
    It could float, of course,
      but would rather

plumb rough matter.
  Airy and shapeless thing,
    it needs 
      the metaphor of the body,

lime and appetite,
  the oceanic fluids;
    it needs the body's world,
      instinct

and imagination
  and the dark hug of time,
    sweetness
      and tangibility,

to be understood,
  to be more than pure light
    that burns
      where no one is --

so it enters us --
  in the morning
    shines from brute comfort
      like a stitch of lightning;

and at night
  lights up the deep and wondrous
    drownings of the body
      like a star.
